A solid object of AISI 302 steel at a temperature of 850 °C is quenched in mineral oil at a temperature of 25 °C. The mass of the solid steel object is 8 kg. The specific heat and density of the oil are 1,950 kJ/kg-K and 890 kg/m3, respectively. The oil is contained in a well-insulated cylindrical tank that has a diameter of 1 m and a height of 1 m.

(a) What is the change in the entropy (kJ/K) of the steel?

(b) Determine the change in entropy (kJ/K) of the oil.

(c) What is the total entropy change (kJ/K) for the system comprising of steel and oil?
